SparkFun Qwiic HAT for Raspberry Pi

Sense HAT is your absolute classic used for a well-known and popular Astro Pi projects. It features set of sensors (Pressure, humidity, IMU and temperature) and a great 8x8 LED screen. It is a full set for your Raspberry - you can both measure your projects environment, display it on the screen as well as manouver and input data with joystick and buttons included on the HAT.

HAT kit with 2 DOF turn & tilt stand designed for Raspberry Pi. Includes the integrated PWM chip PCA9685 that allows RPi to control camera movement, and the TSL25911FN ambient light sensor that detects light intensity through the I2C interface.

Can't stand to run out of pins in your Raspberry Pi? You have a cool new accessory but there's no way to plug it in? If you answered yes to any of the above, then this pHAT could be just for you. This piece has 6 sets of 40 GPIOS - one for your Pi and the rest (5) for your collection of HATs that you might want to plug in at the same time. Use it for a specific project or just to play with several HATs at once.

This HAT is an open source portable sensor that provides the level of suspended particulate matter quantity with its mass. It has a powerful and high-tech PMSA003 sensor that provides the information of suspended particulate matter (PM1.0, PM2.5, PM10) in the air per unit volume.

This module is used to extend the Raspberry's 40 GPIO pins to another set of 2x20 male pins and 8 parallel pins accessible on the terminal blocks in the that test leads are pushed. The electronic board offers great reliability with the Raspberry and is very easy to connect thanks to its existing suitable accessories but not included.
The module offers a set of mini jumpers to configure the GPIO.

16 servo motors with one board seems impossible? With this board not only it isn´t impossible, but it even seems easy. Additionally, you won´t need to sacrifice any of your valuable GPIOs as the HAT connects directly via I2C. Additionally, you have a serial terminal connection at your disposal.

You can supply the power to the board through your Pi or directly if you are going for larger servos and would need a separate source of power. Simply scrap a small blob of solder on the isolation jumper.

T-Cobbler Protoboard Extension Plate GPIO 40 Raspberry PI B+ Pin features:
